Shielded electrical connector with improved insulative housing

Abstract

An shielded electrical connector ( 100 ), to which an electrical element ( 5 ) is electrically connected, includes an insulative housing ( 1 ) defining a number of passageways ( 101 ), a number of terminals ( 2 ) retained in the passageways, a side shield ( 3 ) and a bottom shell ( 4 ). The insulative housing also has a bottom board ( 17 ) defining a number of grooves ( 170 ) communicating with the passageways. Each terminal includes a soldering portion ( 26 ) and a body portion ( 21 ) partially exposed to the groove and straddling over the groove.

1. A shielded electrical connector, to which an electrical element is electrically connected, comprising:
 an insulative housing defining a plurality of passageways and a bottom board, said bottom board defining a plurality of grooves communicating with said passageways respectively, each groove having a length smaller than that of the passageway; 
 a plurality of terminals retained in corresponding passageways, each terminal having a body portion located on said bottom board and straddling over the groove along an extending direction of the body portion for partially exposing the body portion to said groove; 
 a side shield mounted around the insulative housing; and 
 a bottom shell attached to a bottom of said insulative housing, said bottom shell cooperating with said side shield to substantially encase therein said insulative housing together with said terminals. 
 
   
   
     2. The shielded electrical connector as claimed in  claim 1 , wherein each terminal comprises a contact portion extending upwardly for electrically connecting said electrical element, a soldering portion extending from one end of the body portion, and barb portions extending laterally from said soldering portion. 
   
   
     3. The shielded electrical connector as claimed in  claim 2 , wherein said insultaive housing defines a plurality of engaging slits at an inner surface of a pair of periphery walls thereof for engaging with said barb portions. 
   
   
     4. The shielded electrical connector as claimed in  claim 2 , wherein said insultaive housing defines a plurality of slots at an upper surface thereof for extending of tails of said soldering portions. 
   
   
     5. The shielded electrical connector as claimed in  claim 4 , wherein said side shield has a plurality of apertures defined thereon and said tails of said soldering portions extend outwardly through corresponding apertures. 
   
   
     6. The shielded electrical connector as claimed in  claim 5 , wherein said side shield has a plurality of soldering feet formed beside said apertures. 
   
   
     7. The shielded electrical connector as claimed in  claim 6 , wherein said soldering feet are positioned among said soldering portions. 
   
   
     8. The shielded electrical connector as claimed in  claim 7 , wherein said bottom shell is provided with a plurality of soldering tabs staggeredly arranged with said tails of said soldering portions and the soldering feet. 
   
   
     9. The shielded electrical connector as claimed in  claim 8 , wherein the tails of the soldering portions, the soldering feet and the soldering tabs are coplanar with each other. 
   
   
     10. The shielded electrical connector as claimed in  claim 2 , wherein each terminal comprises a U-shaped bending portion and an upwardly projecting neck portion. 
   
   
     11. The shielded electrical connector as claimed in  claim 1 , wherein said side shield comprises a plurality of shielding plates mounted around said insulative housing, and said shielding plates have a plurality of first resilient portions for grounding, a plurality of second and third resilient portions for standing against said electrical element. 
   
   
     12. The shielded electrical connector as claimed in  claim 1 , wherein said side shield is provided with a plurality of mounting portions and said insulative housing defines thereon a plurality of pinholes for insertion of said mounting portions. 
   
   
     13. The shielded electrical connector as claimed in  claim 1 , wherein said bottom shell has a plurality of inserting portions extending upwardly and said insulative housing has a plurality of recesses defined at a bottom surface thereof for insertion of corresponding inserting portions. 
   
   
     14. The shielded electrical connector as claimed in  claim 1 , wherein said bottom wall comprises a plurality of pairs of inner walls, each pair of inner walls being formed at opposite longitudinal ends of each groove for supporting corresponding body portion of each terminal. 
   
   
     15. A shielded electrical connector, to which an electrical element is electrically connected, comprising:
 an insulative housing defining a plurality of passageways and a plurality of side walls, some of said side walls defines slots in a top surface in alignment with the corresponding passageways, respectively; 
 a plurality of terminals retained in corresponding passageways, each terminal having a body portion received in the corresponding passageways, and a solder tail extending outward and received in the corresponding slot for being separated from another solder tail of the adjacent terminal; 
 and a side shield mounted around the side walls of the insulative housing, said shield comprising openings to allow the solder tails to extend outwardly.
